　　Here is an introduction to the cooling system of the wet curtain fan:

　　The wet curtain fan cooling system uses the principle of water evaporation and cooling to achieve the purpose of cooling. The special hydrophobic wet curtain of the wet curtain fan can ensure that the water evenly wets the entire cooling wet curtain wall. When the air penetrates the wet curtain medium, it exchanges heat with the water on the surface of the wet curtain medium to realize the humidification and cooling of the air. The curtain fan is usually installed at the northern end of the greenhouse, and the fan is installed at the southern end of the greenhouse. When the temperature needs to be lowered, the fan is started to forcibly extract the air in the greenhouse, forming a negative pressure, and at the same time, the water pump hits the water on the wet curtain wall. When outdoor air is sucked into the room due to negative pressure, it passes through the gap of the wet curtain at a certain speed, causing moisture to evaporate and cooling. The cold air flows through the greenhouse, absorbs indoor heat, and is discharged by the fan to achieve the purpose of cooling.

　　The above introduction is the cooling system of the wet curtain fan. I hope you can understand it. For more information, please log in: www.dlyunfeng.cn
